Fenestra Continuous Sash Opens Easily
I
T’S not a “strong man’s job” to open the roof sash in the Northway Oakland plant, Pontiac, Michigan, wide enough to get plenty of ventilation.
The long runs of continuous sash in the sawtooth roof are easily opened by the new Fenestra Straight Line Operator.
This operator is so designed that it overcomes the constantly increasing load of the sash as it opens. The heaviest work is done at the start; as the sash opens the labor becomes less.
And the sash can be opened to over 90 degrees—an exclusive feature with Fenestra, either top hung or center pivoted type.
A full description of this new operator will be sent on request. Ask for Fenestra Operator catalog.
